Gunners Cottage was built in the early 1900s and housed many military personnel and their families. From here you can take the 100m path to visit the historic Point Nepean Cemetery or walk the 500m Walter Pisterman Heritage Walk to the remnants of the former quarantine cattle jetty.

At Observatory Point there is a picnic area and views of the Bay. Return via Coles track to complete the circuit. Car parking is available at the Quarantine Station or Gunners Cottage (cars are not permitted past this point).
